Patent GB-2230670-A (GB)
Title: Extracting carriers
Inventor: HAWKES HENRY WILLIAM
IPC: H04B1/30
Filed: 1989-04-21
Abstract: In a method of extracting the two carriers of two A.M signals forming a composite input signal with only one tuning operation, one sinusoidal carrier is first extracted at 1 and mixed with the composite signal at 3 to generate a signal sin  OMEGA  beta t at the difference frequency between the two carriers which is then squared in a hard limiter 5 and further processed e.g. at 16, to derive a sinusoidal signal at the difference frequency which is combined at 7 (SSB generator) with the first carrier to derive the other carrier. The processing circuit may be a low-pass filter if the amount of residual modulation is acceptable or a multiple phase lock loop including a VCO 15, frequency discriminators 13, 24 and a controllable phase shifter 19 when residual AM modulation and time variant phase modulation are to be removed. The arrangement 16 enables the output of VCO 15 to be phase locked to output of limiter over a wide range of phase variations. Phase shifts within generator 7 may be compensated by a controlled phase shifter following mixer 23. One of the carriers is a strong signal and the other a weak signal. Alternative arrangements for the circuit 16 and the controlled phase shifter are disclosed. <IMAGE>
